To @ZZ @Unomat may concern:

Be it known thatwe, SvnN Pj-ALQmsnpf Sedalia, Pettis county, Missouri,and ALLAN accompanying drawings, forming apart of this specification.

This invention relatesfto improvements in Y freight car constructiom andmore particularly to an improved arrangement of inside `doors adapted-to both protect the outside door from shifting' loads and-to serve as agrain door.V

Other and morespeciiic objects of the'invention are to provide anAarrangement ofv thecharacter above indicated so designed y Y that thethreshold andthe door posts of the ca r yare 'strengthened' andreinforced by means oi plates which are also arranged -to c operateand'unction with the inside door;

to y provide simple, automatically operated Y V4a pair of plates 2O and21, the'formerbeing means for locking the inside door 'in'.itsdifferentpositions; and tov provide simple means for opening the insidefdo'orbyvusing Aa pinch'baror other similar vsuitable tool.

The invention furthermore n consists'` in improvements in the parts and'devices and in the novel combination of the partsv and devices hereinshown, described or claimed.

In the drawing forming Aa part of thisV specification, Figure 1 is asidefelevation of a portion of a freight car showing `our improvementsin connection therewith.Y Fig. 2 is ahorizontal sectional view taken onthe line 2 2 of Fig. 1. Fig. 3 is 'a vertical sec-V tion takensubstantially on the line 3 3 of Fig.v 1. Fig. 4* is an inside elevationof the car, the full lines illustrating the position A of the insidedoor in closed position, andthe dotted lines the position of thedoor.when open or in inoperative position. Fig. 51is Va Vdetailed vi'ew,-upona largerv scale, illustrating more particularly'the .latch forlockingthe door in its different positions. Figs. 6

and 7 are detailed sectional views taken on the lines 6,-6. and 7 7respectively of Fig...v

5. And Fig. 8 is an enlarged horizontal sectional view takensubstantially on the line 8 8 of Fig. 1.v

Referring to said drawing, lOvdenotes the` side wall of the carhavingjthe usual' door f indicated in Figs. l, 2 and 3 at 14 to accom-'modate al'ush outer door (not shown): 4The `improved inside door isindicatedat land,

The door 15 is slidablyxmounted; between mounted on the floor of thecarfand extending over-*the threshold asl indicatedat 22 to *therebyreinforce the latter and minimize wear dueto trucks, etc. The* plate201s provided with alongitudin'ally extending central groove23 `in whichthe lower edge vof the Vdoor -15 slides. The upperplate 21 is bolted oriotherwise ysuitably secured to the .inner wall of 1 the car and isfprovided of the door. The plate 20, as shown, is provided Vwith upwardextensions 25,?and26 at the opposite sides ofthe-door opening, saidextensions being secured to the inner'faces oiV the door posts.12 tothereby strengthen Y the latter `and preventxexcessive wear there'- of.'Iheportions'^`A 25V and 26.v arefshownroas extendingonly a 'relativelyshort distance. Y Y V'up the post112,butasfwill be-understood by f.those skilled in the art, these portions may be made of any desiredlength to suit varyingconditions. YThe'left-hand post 12, as

inner side thereof with a vertically extend- K`-` 1 'viewed in'Figs. 1and 2, isA provided on the from the use of nails and strengthens it, butl@ l 11o Y Y has formed thereon a flange 29 to vthereby provide avertical groove within which is received the advance doubled over edge8O of the door 15 to form a grain seal when the door 15 is in closedposition. Said plate 28 is also provided with a horizontal extension atthe top as indicated at 27 to fit over the in which seats the hookedshaped vertical rear edge 12 of the door 16 to form a grain seal. 1

In order to retain the door 15 in either 'closed or open position, .wehave provideda pivoted latch or .lock 31 mounted in a bracketl 32counter-sunk into one of the posts 12, as clearly indicated in Figs. 1,5, 6 and 7.V r1`he upper edge of the door 15 is provided withV twolnotches 33 and 34, the

Vformer near theadvance edge of the door Y and the latter near the rearedge -so that, when the door is in closed position, theV gravity latch31 will drop into the notch 34 :and hold the door closed and when thedoor is in open position, said latch will vfall into the notch 38 andhold itin said position. The bracketl 32 is provided with Va taperedsocket 33 which will permit the latch 31 to swing vupwardly to therebyclear the door, as-is apparent from Fig. 7. To open the door'15whenthere is any pressure thereon from the interiorofthe car, the latch 34Cis, of course, first lifted and then a pinch bar .or other suitable toolis inserted between the shoulder 34e on the door 15 and thea'djacentportion 25 of the reinforcing plate 22. As clearly appears fromFigs. 2 and 8, the shoulder 34:', which maybe in the form of a shortsection of angle iron riveted or otherwise secured to the door, yis sollocated as to provide suliicient clearance 35 to permit the insert-ionof the tool for prying the door open. The shoulder member 34, beingapplied to the counter-sunlror dished portions of the door 15,will clearthe right-hand postl 12, as viewed in Fig. 2, Awhen the door 15 is open.

From -the preceding description, it will be seen that the arrangementwhich we have provided is well adapted for the purpose of protectingtheoutside door from shifting "loads inwthe car and consequent damagethereto,` since the door V15, being dished inwardly and corrugated, is.exceedinglyV strong for its weight'and lis thereby also well designedfor use as a grain door. Vhen used las a grain door, a grain seal is fquent cause of damage to the car.

Although we have herein shown and described what we now consider thepreferred embodiment of our invention, the same is merely illustrativeand we contemplate all changes and modifications that come within thescope of the claim appended hereto.

In a car having a door opening-in a side wall thereof, defined by sideposts, threshold and lintel, the combination with a door horizontallyslidably mounted on the inner side of said wall, of fixed means,disposed out Vside of the door opening arranged to thereby lea've thelatter unobstructed, coperable with the side and bottom edges of thedoor to form a grain seal therewith when the door is Vin closedposition, said door ben .c f 4ing iormed of sheet metal and having acentral, corrugated inwardly dished portion and flat marginal portions,the latter adapted lto vslidably bear against the inner face of said'side wall, said doorhaving an auxiliary relief door disposed within thearea of the dished portion and inwardly of the plane defined by saidflat marginal portions to thereby avoid interference when the door ismoved to one side of the door opening hack of the side wall of the car.A
